First-line therapy for an acute flare of inflammatory bowel disease is which?

• A. Corticosteroids
• B. Antibiotics
• C. Proton-pump inhibitors
• D. Iron supplementation

Answer: (A)

An acute inflammatory bowel disease flare is best controlled initially with systemic corticosteroids because they rapidly dampen the broad inflammatory response driving symptoms. Corticosteroids blunt multiple parts of the immune cascade, reducing proinflammatory cytokines, inhibiting leukocyte migration into the gut, and stabilizing vascular permeability. This leads to quicker relief of key symptoms like abdominal pain, diarrhea, and rectal bleeding compared with many other options, which is crucial when a flare is moderate to severe and needs fast control to prevent complications.

Antibiotics aren’t a routine remedy for typical flares since they target infection rather than inflammation, unless there’s a specific infectious component or complication. Proton-pump inhibitors don’t address the inflammatory process in IBD either, and iron supplementation treats anemia rather than active inflammation. After remission is achieved, the plan is to taper the steroids and move to longer-term, steroid-sparing therapies to maintain control with fewer systemic risks.
